To all whom it may concern:

Be it known that I, RAYMOND G. Force, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Automatic Hog-VVatering Troughs, of which the following is a specification.

My invention relates to watering-troughs, especially adapted for animals, such as hogs, which are prone to roughness and have a strong propensity to invade the trough, either through greed or for supposed convenience to partake of the contents or to wallow.

To meet these conditions the essentials are strength of the trough structure, its barrierlike and limiting shape, its sufficient ca pacity, and its automatic supply of water proportionate to consumption. These are the objects of my invention, and to this end my invention consists in the novel automatic hog-watering-trough which I shall hereinafter fully describe, by reference to the accompanying drawings in which Figure l is a top plan of my trough.

Fig. 2 is a broken elevation 01 the same.

Fig. 3 is a broken elevation showing a modification in the shape of the barrier wall.

The trough comprises essentially a rela tively heavy cast iron base 1, to insure stability, and a relatively light sheet-metal barrier and limiting wall 2. In the most practical form the base is circular and the wall is cylindrical; but polygonal forms might be used, though with some disadvantages in manufacture and less economy 1n use.

The base 1 is formed with a raised rim 1 and an inner flange 3 concentric with its rim; and the Wall 2 is secured to this rim as shown at 1, so that said wall, thus set, forms an annular space 5 for the water. The diameter of the wall is so proportioned to that of the base that the water space 5 has a width too small to permit the hogs getting into it and its circular form is pro hibitive of any attempt to lie down in 1t; and moreover this form gives the maximum capacity for approach, due to the hogs assuming radial lines in partaking of the water.

The wall 2 is relatively high so that the hogs cannot surmount it. The top of the wall is open, as seen in Fig. l, to enable the attendant to inspect the interior operative mechanism for the automatic water supply and to adjust or repair the same. The flange 3 of the base about which the wall is fitted, is at one ortion indented to form a chamber 6 in w ich is a float 7. At another portion said flange is indented, as shown at 8, to form a supply chamber communicating with the trough space, and into which chamber a water connection in which is a controlling valve 9, discharges, said connection being supplied by a pipe 10 from a source of water, said pipe rising Within the open space of the annular base casting. The float 7 is connected with the valve 9 by a lever arm 11. It will thus be seen that the automatic supply mechanism is fully housed within and protected by the wall 2.

The operation and use of the trough is as follows As predetermined by the relation of the float to the inlet valve, the water will rise to a given level in the annular water space 5. The hogs will line up radially to said space. They cannot get into it, nor wallow in it, because of the barrier or limiting wall, nor can they dislodge or upset it, be cause of its inherent stability. As they drink, and the level of the water in the space 5 lowers, the float drops and by open ing the valve admit-s more water, thereby keeping the supply automatically constant.

As shown in Fig. 3 the barrier Wall may assume the form of a cone 2. This form will house the water connections, but is not as eflicient in keeping the hogs out of the water space, as the cylindrical form.

I claim A hog-watering device of the character described comprising a heavy base portion of cast metal adapted to be self supporting upon the ground and bearing thereon over an extended area to prevent tipping under actions of the hog, said base having an outer rim portion projecting upwardly from its bottom and an inner flange portion also projecting upwardly from said bottom, the flange being spaced from the rim to coop crate with the intervening portion of the bottom in forming a trough therebetween, the flange at one portion being indented to form a float chamber and at a separate portion for a water supply, a valved water supply associated With the last mentioned indented portion adapted to feed to the.

trough; a fio'at in the fioatchamber arranged to be influenced by the Water in the trough, operative connections bridging the .wallof the indented flanged portion of the float chamber and extending between. the float and the valved Water supply to control the latter from the float, atsheet inetal barrier:

munioation between the trough and the float chamber, a portion of thebarrien also occupying. a, plane outwardlybeyond; the edge ofthe float to house the seine. relative to the-openportionrof the trough, and means for securing the sheet metal barrier to the flange of the cast base.

In testimony whereof I have signed my name-to this specification in the presence of two subscribing witnesses.
